Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of table cutting devices with battery packs face inconvenience in monitoring the remaining electric quantity, as they need to suspend the cutting stroke and bend to observe the battery pack's display, disrupting the cutting process.
Innovation Solution
A table cutting device with a display assembly that shows the battery pack's electric quantity information from a distance greater than or equal to 5 mm, allowing operators to view this information without needing to bend or suspend the cutting stroke, featuring a light-emitting portion for conveying electric quantity and failure information through light emission and indicator bars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display assembly is integrated close to the battery pack, then the structure is compact, but the operator cannot observe electric quantity information without bending and suspending the cutting stroke
Solution Approach 1:
The patent introduces an optical transmission component (transparent window or light guide) as an intermediary between the battery pack's display and the workbench surface. This mediator transmits light from the battery pack's display to the workbench, allowing the operator to view electric quantity information without directly observing the battery pack, thus eliminating the need to bend and suspend the cutting stroke.
Solution Approach 2:
The patent replaces the mechanical requirement of the operator bending down to view the battery pack display with an optical transmission system. The light emitted by the battery pack's display is transmitted through the transparent window to the workbench surface, converting a mechanical observation task into an optical information transmission process.
2Ease of operation
If the display assembly is positioned on the workbench within reach of the operator, then the operator can view information without bending, but the distance from the battery pack increases
Solution Approach 1:
The transparent window embedded in the workbench serves as an intermediary that optically connects the battery pack display to the workbench surface. This mediator allows light to travel from the battery pack (at one location) to the workbench surface (at another location), enabling the display information to be viewed at a convenient position without requiring the operator to bend, while the physical distance between components is accommodated through optical transmission.

AI summary
A table cutting device includes: a workbench (120) on which a workpiece is capable of being placed; a cutting assembly (20) capable of performing a cutting operation on the workpiece; a drive assembly (40) including a motor (430) and driving the cutting assembly (20) to move; and a power supply connection assembly (60) for connecting a battery pack (3), where the battery pack (3) supplies an energy source to the table cutting device. The table cutting device further includes a display assembly (52E, 52) capable of displaying an electric quantity of the battery pack (3), where when the battery pack (3) is mounted to the table cutting device, the distance between the display assembly (52E, 52) and the battery pack (3) is greater than or equal to 5 mm. The table cutting device has the additional display assembly (52E, 52) so that an operator can observe electric quantity information of the battery pack (3) when operating the table cutting device, thereby greatly improving operation convenience.
